| Our surveys have shown that
roughly 50% of homes in urban areas use household water purifiers;
for this reason, R&D aimed at more advanced, next-generation
water purifiers that are designed to meet changing environmental
conditions has grown increasingly important.
Mitsubishi Rayon has a varied lineup of products which remove all of the 13
Substances to be Removed as specified in the Household Device Quality Display
Law, including trihalomethane, lead, mold odor, and agricultural chemicals.
We have developed and put on the market CSPX, which attaches directly to the
faucet, our on-the-counter type EMINENT II, our under-the-sink type
alkali ion water purifier CLEANSUI U-AL680, and our on-the-counter alkali
ion water purifier Alkali AL001. Further, we have been striving to develop products
with excellent design for uses away from the sink, such as our pitcher-type
water purifier CSP4. |

| While we have focused on
water purifiers for household use, we have also developed
and brought to market the MP02 water purifier, designed for
use by restaurants and other establishments, so that the benefits
of clean water may be enjoyed outside the household too. |

We are aiming to expand and create markets
for water purifiers related products for use in bathrooms,
sinks and anywhere in the house, that will improve the living
standard. We currently marketed such products as the PURE
PURE series of dechlorinating showerheads and BATH DE PURE
PURE, dechlorinating attachments for bath taps, and our R&D
is aimed at expanding our range of products in this area.

A smaller device for household
CC CARBO |
In 1998 the Mitsubishi Rayon Group joined
a balneotheraphy organization established by a number of medical
researchers, in the role of device developer and manufacturer,
and since that time we have engaged in a variety of research
activities. The Mitsubishi Rayon balneotherapy devices (MR
artificial carbon dioxide spring) series have been developed
and produced based on the fruits of this research using a
special hollow fiber membrane. Because this membrane is gas-permeable
but does not allow liquid to pass through, carbon dioxides
gas dissolve efficiently in warm water. These are the first
devices worldwide that enable the production of bathwater
with a super-saturated level of carbon dioxide (over 1000
ppm). The primary model in this series has been CARBOMEDICA,
which is designed for use by medical institutions. We have
also developed and brought to market CC CARBO, a smaller device
for household use, a full-body bath device for commercial
use, and a full-body bath device for household use. These
devices are being utilized not only in households, but in
a broad array of fields, ranging from spas to sports. |

| As environmental issues are
concerned, it is critical that water treatment technology
provide devices with greater capabilities and more compact
size, in order to address these problems on a global scale.
Membrane bioreactor (MBR) processes, which were developed
for this purpose, are now recognized as a standard treatment
technology.
Mitsubishi Rayon has conducted complete development, from the hollow fiber membrane
to the usage technology, and as a result our MBR hollow fiber membrane maintains
a large share of this market, even being used in manufacturing plants. Starting
in April 2005, at our Toyohashi plant, we have been manufacturing our new hollow
fiber membrane Sterapore SADF TM for use in waste water treatment. Sterapore
SADF TM is recognized for its high water purifying capability and durability,
and for its outstanding resistance to chemicals, and we have received many inquiries
concerning it both from within and outside Japan. In South Korea and China its
use in some of the largest MBR facilities in the world has been decided. In
the future we expect to build on this market record and expand our share in
the waste water treatment field further. |

| The problems faced by Japan’s
water supply include the difficulty of water purification
caused by the deteriorating quality of water sources and the
problem of securing land for use as water
purification plants. The academic, public and private sectors
have joined together in research to solve these problems.
Since 2002, R&D under the framework of the e-Water Project
(R&D directed toward water purification technologies with
reduced environmental impact) has focused on membrane filtration
devices for large-scale water purification plants. In addition
to our participation in the e-Water project, we have made
use of our expertise in this field to develop STERAPORE LFB,
a large-scale infiltration membrane module. We are also engaged
in R&D aimed at developing and expanding markets for a
wide range of water purification products for large-scale
purification plants, small-scale plants, and filters for water
supplied to factories. |
